The Multiquip 11056 Cylinder Head Bolt is a genuine OEM fastener designed for C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith series concrete pumps. As a factory-sourced component, it is manufactured to the exact specifications required for correct clamping load and head gasket integrity on these machines. This bolt is a direct fit for the cylinder head assembly, requiring no modification to install. Contractors and service technicians relying on C30HDNI and C30HDN equipment can trust this part to restore the head assembly to proper operating condition.
Key Features
- Genuine OEM Specification: — Manufactured to the exact thread pitch, grade, and length required for correct cylinder head clamping force — critical for maintaining a proper combustion seal.
- Direct-Fit Installation: — Engineered to seat correctly in the cylinder head bore of C30HDNI and C30HDN concrete pumps, aligning with OEM torque sequences without reworking the mounting surface.
- Broad Series Compatibility: — Confirmed fitment across C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith concrete pump models.
- Combustion Integrity: — A correctly torqued cylinder head bolt maintains head gasket compression, preventing coolant or combustion gas leaks that can cause overheating or loss of pump output.
- Safety-Critical Fastener: — Cylinder head bolts are structural fasteners under sustained thermal and mechanical stress; using the correct OEM-grade bolt is essential to prevent head warping or catastrophic gasket failure during operation.
A cylinder head bolt secures the cylinder head to the engine block, compressing the head gasket to create a sealed combustion chamber. It must withstand repeated cycles of heat expansion and mechanical vibration without losing clamping force. When a cylinder head bolt stretches, corrodes, or breaks, the head gasket seal is compromised — leading to coolant loss, compression drop, overheating, or engine damage that can take the entire pump out of service.
